An interesting thing about teaching is the delayed effects it can have. Just this week, I heard from one of my old students asking for a referral to help with a personal difficulty. It’s been some years, but the phrase “Of all the people I know, you’re the only one I could think of who could help me” was used. I was able to point him in the right direction.
This isn’t the first time this has happened, and it’s very gratifying to have people you taught reach back to you for assistance. I hope they remember the other stuff I taught them, like the four rules, because that will be useful life-long.
